  A. Confidentiality
  B. Resistance to Jitter
  C. High Availability
  D. Data Integrity
  A. Confidentiality

• Question 722:

  Which of the following is the OSI layer that handles file compression such as LZMA or DEFLATE?

  A. Layer 3
  B. Layer 5
  C. Layer 6
  D. Layer 7
  C. Layer 6

  ---

  The presentation level is translator between the application and network format. Unlike the lower layers, its concern is with the syntax and semantics of the information transmitted. Most user programs do not exchange random binary bit strings. They exchange data such as names, addresses, dates, etc.

  Different computers store the data in a different way. In order to allow these computers to transmit the data to each other the presentation layer translates the data into a standard form to be used on the network. Another function is data compression which can be used to reduce the number of bits needed to send the packet of information. Security is also added at this layer by using data encryption and decryption. This prevents others from intercepting the data and being able to decipher the meaning of the bits.

• Question 723:

  A. Various router commands
  B. Access control lists
  C. Certificate services
  D. A RADIUS server
  C. Certificate services

  ---

  A PKI (public key infrastructure) enables users of a basically unsecure public network such as the Internet to securely and privately exchange data and money through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. The public key infrastructure provides for a digital certificate that can identify an individual or an organization and directory services that can store and, when necessary, revoke the certificates. Although the components of a PKI are generally

• Question 726:

  Which of the following protocols works at the LOWEST layer of the OSI model?

  A. L2TP
  B. PPTP
  C. ISAKMP
  D. IPSec
  A. L2TP

  ---

  Layer Two Tunneling Protocol (L2TP) is an extension of the Point-to-Point Tunneling Protocol (PPTP) used by an Internet service provider (ISP) to enable the operation of a virtual private network (VPN) over the Internet.

• Question 727:

  A network technician is sent to troubleshoot a phone line in the building. The user reports a dial tone is not available when attempting to place a call. Which of the following tools should the technician utilize in this scenario?

  A. Protocol analyzer
  B. Punch down tool

• Question 728:

  A NAS appliance has had a failed NIC replaced. Now the NAS appliance is no longer visible on the network. Which of the following is the MOST likely cause of the problem?

  A. The network cable connecting the NAS to the network switch is bad.
  B. The network port that the appliance is connected to is assigned to the wrong VLAN.
  C. Port security on the Ethernet switch has disabled the port.
  D. Firewall needs to be updated for the new NAS device.
  C. Port security on the Ethernet switch has disabled the port.

  As by port security switch find the changes in mac address because nic is replaced so due to security reason switch shut that port.

• Question 729:

  Which of the following is the Telco end of a T1 demarc?

  A. Smart jack
  B. Network tap
  C. Proxy server
  D. IDF
  A. Smart jack

  ---

  Smartjacks provides diagnostic capabilities. A very common capability provided by a smartjack is loopback, such that the signal from the telephone company is transmitted back to the telephone company. This allows the telephone company to test the line from the central office, without the need to have test equipment at the customer site. The telephone company usually has the ability to remotely activate loopback, without even needing personnel at the customer site. When looped back, the customer equipment is disconnected from the line.
